PATENT DITRIBUTINli-GEAR FOR EXPLOSION-MOTORS.

Ne -scam;

man Em eror, and residing at 'Erfurt, 1--

Dorothecnstrasse,' ih theKingdom of Prussia, German Em ire,' have' invented certain new and useful mp'ro'vements in Distributing- Gears'forExplosion-Motors, of which the followmgis'aspecification.

This inye'ntion relates to a distributing gear foneXp'l'osion-motors, and ,n1y ..improv'cmeats in such relate to certain combinations'antl arrangements of parts, as are.

fully describedhereinafter.

In order to-make my invention more clear I refer the accompanying drawings. in which similar letters [denote similar parts throughout the several views and in which Figureil'is h-view6f an explosion-motor having my improved distributing gear applied to it some parts being shown in section;

the motor, only the chief parts being shown; Fig. 31s a frontal-view of a cylinder forming 353 part of the gear, in connection with some other parts which will all duly be referred to I z the specification. Fig. 4 is-a planof the ..s'tssho'wn in.Fig."3, and Fig. 5 is a frontiew of 'said parts, the eccentric grooved disk being shown in section. Fig. 6 is a view similar to 5, showing the position of the rod-1(f) for. actuating the tongue (2).

The distributing gear is intended for motors working after the four-stroke cycle, and the ob'ect'of my im rovements in gears of such a 'nd is to simp 'fy the means whereby the speedof the motor i's'regulated. Iattain this, first, by providing the cylinder 11 Figs; 1 and 2 which is keyed to the shaft a and driven by the same with two circumferential groove s g-g having a crossing 10, Fig. 2. The lever c, Fig." 3, actuated by the grooves of cylinder is fulcrumed at e and has a shoe (1 Fig. 5 sliding in the grooves g g, in such ama:nner, that the lever is operated b mediation of this shoe as soon as the e 0c is made to pass fromthe groove .9 into the groovafi and reversely. is effected by a swior tongue 2 connected by a pin Fig; .fi, with short'horizontal r0 j guided in the cylinder 1) and being under the action of a spgu'fy which constantly tends to force the "re grooved displaceable disk r attached by feather-and groove to theshaft 'a. 0 The dis 1' is coupled y means-of pins p, Fig. 3, with I I Specification of Letters Patent.

lever c ,is not only moved laterally bythe shoe dbut is also movedvertic'all together with the lever h. The free end of t e latter is so shaped (see Fig. 4)" that the free end of the lever c is always supported. This end is fun nished with an adjustable screw 1 adapted to act upon the valve-rod 1' when the position of the lever c is that shown inFi 4. If, however, the shoe d of the lever '0 ated by the switch of the governing-device of the motor, the screw lis kept off the.valve- .been devirod i and the valve is thus not actuated at tors-Patent of the United States is:
